  1. Hi Vlaiv, Thanks for your reply pal. Ok so all in all what is my best option? I am keen to image galaxies so would prefer not to change for a shorter FL imaging scope. Maybe a guide scope with a longer focal length, or what about a OAG. I'm not familiar with OAG and what the advantages a nd disadvantages are. My current payload is 7kg so adding a larger guide scope will put me close to the limit. Hmmm decisions decisions, what do you guys advise? Thanks again all. Ryan
  2. Thanks for the graph Carole, however it displays an error when I click it. PhotoGav, I am patiently waiting for a gap in the clouds to record a PE curve. I am hoping it will help me further. I will stick at it especially now I understand image scale etc thanks you everybody's help Much appreciated guys. Ryan
  3. Hi Carole, That's amazing!!! What camera are you using? I love the WO scopes, I had a Z61 when I had a Star Adventurer. I may sell the 100ed and go for something a little smaller. Ryan
  4. Hmmm 0.58 is a pretty ambitious number to achieve. I presume that's the total RMS is it or 0.58 on RA & 0.58 DEC? Now I am thinking maybe a shorter focal length scope for example the 80ED would result in 2.61"pp, therefore anything below 1.3RMS would be fine. Thanks pal
  5. Thnaks for your replies guys. Currently I am using a modded Canon 600d with a resolution of 1.16"pp. Can anybody tell me what sort of RMS I would need to be achieve good guide results? Am I correct in saying I cant change the binning of a dslr? Thanks again all
  6. Hi guys, I currently have a HEQ5 Pro belt modded, polemaster, 100 Ds Pro Evostar all guided with an Antares 60mm guide scope/Altair Gpcam2 AR0130M. I was wondering how long people reliably guide for with similar setups/focal lengths. The focal length of the 100 DS Pro scope with the reducer is 765mm. Thanks all Ryan
  7. A stunning effort Pepe. What focal length and camera did you use for your image. Also do you recomend a particular length of exposure? I am hoping to image it this month. Thanks Ryan
  8. Hi pal, Am i right in saying they will fit the SW 100Evostar DS Pro? Thanks Ryan
  9. Hi pal, thanks for your reply A 12v car adapter sound good, they range anywhere between £7 to £50. What price was yours? Cheers
  10. Hi all, I am in thr middle of assembling my out in the field set up. I will be using a Sony Vaio laptop (19.5v), HEQ5 Pro and a guide cam. I have a seprate 17ah Sky Watcher power tank for two dew straps. I will be doing all my imaging out in the field, so i need a reliable high powered battery that will maintain power (particulary for my laptop). I jave read some power packs are u able to maintain power whilst the laptop is on. If anynody has experience and able to advise me on a tried and tested battery, it would be hugely appreciated Thanks Ryan
  11. Looks awesome!!! I want the 100mm version £££
  12. Hi guys, I am following this thread with interest. I am looking for a decent refractor (80mm-110mm). At the moment I am using a modded canon 600d witht the aim to own a ccd/cmos camera in the future. Looking at the astronomy tools fov calculator, with the 80mm/100mm Evostar Im yielding a 4.30pixel size. Im torn between 4 potential scopes. Either the Evostar 80mm/100mm or both the Altair Starwave 80/102mm. Adam J, what did you go for after? Thanks Ryan
  13. Hi pal, Thank you for your help and advice I currently image using a DSLR (Canon 600D modded), this gives me a 4.30um pixle size using the astronomy tools fov calculator and various apos. Is this not worhy of producing satisfying images of galaxies? I hope to purchase a dedicated ccd/cmos imaging later in the year so will keep pixle sizes in mind before choosing a scope. I totally agree with your suggestion about the 2nd hand market The new Sky Watcher EDS Pro series seem decent value for money, however I'v read that their focuser's are pretty naff Thanks again Ryan
  14. Hi all, Can anybody reccomend a good all round apo that sits somewhere between 600mm-800mmish. Something that will give me close enough images of galaxies with the off nebula or 20 lol. I have recently purchased a modded HEQ5 Pro & would like a decent scope that will give me nice images. I have recently sold my Zenithstar 61mm, the FPL53 glass gave me some lovely images. I have to take into account focal reducers/flatteners (ideally a scope with a matchihg field flattener, as I dont want reduce the focal legth). G Does anybody have experience in using similar apo's without FPL53 glass? My options/budget are pretty good if I dont go for FPL53 glass, however I dont want to go to far backwards (if I can help it). Budget is around the £800ish mark. I would be ever so greatful if anybody can help me. Thanks Ryan

    4" Apo bargain.

    Seems a bargainI am in the middle of looking for a 80-110mm apo. Will there be much of a difference in image quality between an FPL53 doublet and these types of triplets? I have a budget of £800 give or take, ideally I dont want to go lower then 650mm. Finding an FPL53 wuth similar spec is probing difficult. Thanks all.
